clone 이미지를 하나 생성해서 docker 설치

주소는 211.183.3.110 으로 하여 현재 구성된 사설 저장소에

간단한 my_httpd:1.0 이미지를 push 해보세요!

base image = httpd

Using default tag: latest
The push refers to repository [211.183.3.100:5000/my_httpd]
Get "[<https://211.183.3.100:5000/v2/>](<https://211.183.3.100:5000/v2/>)": http: server gave HTTP response to HTTPS client

    이건 안 된 거다.

    현재 저장소는 HTTPS연결만 허용되어 있어 HTTP 연결이 불가능하다. 따라서 insecure한 연결(HTTP 연결)을 허용해야 한다.

  8. root@ubuntu:/docker/regi# vi /etc/docker/daemon.json

    {
    "insecure-registries": ["211.183.3.100:5000"]
}

    정확히는 인증서 없이 연결하겠다는 뜻.

  9. root@ubuntu:/docker/regi# systemctl restart docker

    설정 바꿨으면 뭐다? 재시작이다 ㅇㅋ? 유남쌩?

여기까지 하면 대략 다음과 같은 구조다.
